结合黄河部分大型水库工程实测资料及还原计算成果 ,探讨了洪水资料还原中水库调蓄量的计算方法、成果间的差别和原因以及水库入库 (坝址 )断面和水库下游断面洪水过程线还原计算方法等问题 ,并对水文观测比较薄弱的广大中小型水库工程在还原计算上所面临的困难提出了应及早研究解决的意见。 Based on the measured data and calculation results of some large-scale reservoirs in the Yellow River, the calculation methods of reservoirs in flood data reduction are discussed. The differences and causes of the results are also discussed as well as the reduction of the flood process line in reservoir storage (dam site) Calculation methods and other issues, and the hydrological observation is relatively weak in the majority of small and medium sized reservoirs in the calculation of the difficulties faced by the proposed research should be resolved as soon as possible views.
